WebFeb 20, 2024 · Recursion: In programming terms, a recursive function can be defined as a routine that calls itself directly or indirectly. Using the recursive algorithm, certain … WebMay 20, 2024 · A recursive filter is just one that calculates a new, smoothed value (y n) by using the last smoothed value (y n – 1) and a new measurement (x n ): y n = w × x n + (1 – w) × y n – 1. The amount of smoothing is controlled by a weighting parameter (w). The weight is a value between 0% and 100%.

Exponential smoothing is a rule of thumb technique for smoothing time series data using the exponential window function. Whereas in the simple moving average the past observations are weighted equally, exponential functions are used to assign exponentially decreasing weights over time. It is an easily learned and easily applied procedure for making some determination based on prior assumptions by the user, such as seasonality. Exponential smoothing is often used for anal… WebMay 1, 2009 · Introduction This paper axiomatizes and investigates a model of recursive preferences over intertemporal plans, extending the smooth ambiguity model developed …
